Abstract
A multi-channel optical device and method of making the same are disclosed. The optical device includes a plurality of detectors on a detector mounting substrate, and a corresponding plurality of lenses on an interior surface of the optical device. Each detector detects light having a unique center wavelength. Each center wavelength corresponds to a channel of the optical device. Each lens focuses light towards a corresponding detector. Each detector has a location corresponding to a focal point of the light focused by a corresponding lens. The method of making the optical device includes placing lenses on a surface of the optical device housing, transmitting light having a plurality of center wavelengths through the lenses, determining locations on a detector mounting substrate where each light beam is focused by a lens, and placing a detector at each location.
